Loading OPENJDK and Oracle JDK at openSUSE 13.1

The usual working machine is openSUSE 13.1. After replacing it with Oracle JDK, the INTELLJ interface became invisible, did not want to debug and then uninstalled the Oracle JDK and reinstalled the OPENJDK.

[Uninstallation of Oracle JDK]

1. Query Package Name

Rpm-qa | grep Java

The name of the query to the Oracle JDK RPM installation package is Java-xxx-fcs.

2. Uninstall

Rpm-e Java-xxx-fcs

3. Delete Related environment variables

Remove the environment variables such as/etc/environment or Java_home in. bashrc.

This allows the Oracle JDK to be removed.

[Installation of OPENJDK]

1. Run the following command.

sudo  in-F java-1_7_0-openjdksudo in-f java-1_7_0-openjdk-devel

The first package is a JRE.

The second package is a JDK.

The installation path is located under/usr/lib64/jvm/and the current stable version is 1.7.0.

2. Set environment variables.

The java_home of OpenSUSE 13.1 should be set in/etc/environments:

Java_home="/usr/lib64/jvm/java-1.7.0"

[Uninstall of OpenJDK]

Remove the ' java_home ' environment variable and uninstall the relevant package by completely reversing the installation steps.
